It's difficult to get pregnant, but as long as you pass these three levels, you can wait for the baby to be born? Which three levels?

Pregnant mothers will have a variety of pregnancy reactions during pregnancy, and most pregnant mothers will have different degrees of discomfort due to fetal development. Although it is not a good experience for pregnant mothers to accept a certain pregnancy response, pregnant mothers will still bite their teeth for the health and safety of the fetus. In fact, pregnancy is not only a test for pregnant mothers, but also a test for the fetus. During pregnancy, the fetus will grow from a small fertilized egg to a baby weighing 5-8 kg. So pregnancy is like a "monster upgrade" for the fetus. Only by passing all the checkpoints can you meet your mother safely and healthily.

It's difficult to get pregnant, but as long as you pass these three levels, you can wait for the baby to be born? Which three levels? During pregnancy, pregnant mothers may feel very difficult because of the influence of pregnancy and worry about the fetus. Because pregnant mothers not only accept the "destruction" of pregnancy repercussions physically, but also worry about the health and safety of the fetus mentally.

During pregnancy, generally speaking, as long as you pass these customs, it means that the fetus is basically safe and healthy. Pre-pregnancy: Pre-pregnancy is the main period of fetal organ decomposition, and the neural tube of the fetus develops very rapidly at this stage. Moreover, due to some uncertain factors, the fetus is likely to have fetal arrest. The common conditions leading to fetal abortion are: mother factor, father factor, external force factor and embryo factor. These reasons may be abnormal in the process of fetal development. After the abnormal attack, the fetus is likely to miscarry in the first trimester.

Second trimester: NT and Down's screening. Strictly speaking, it belongs to pre-Tang screening. Pregnant mothers can go to the hospital for nt screening during the pregnancy of 1 1- 14 weeks, and check the thickness of the posterior transparent layer of the fetal neck by B-ultrasound, so as to judge the possibility of fetal chromosome diseases according to the thickness. Generally speaking, as long as it is less than 2.5 mm, it belongs to the normal state, and as long as it is greater than 3 mm, it belongs to the abnormal state. If the result is more than 2.5 mm and less than 3 mm, further inspection is needed. Down's screening is used to check whether the fetus has the possibility of Down's syndrome. In a sense, Down's screening belongs to the mid-Tang screening.

Down's screening is a project to check pregnant women's blood. The viewing time is between 15 and 20 weeks. If the result of Down's screening is high risk, it means that the fetus is more likely to suffer from Down's syndrome. If the result of Down's screening is low risk, it means that the fetus is less likely to suffer from Down's syndrome. As for critical risk, it means that although the results are within the normal range, the data has now reached the edge of the normal range, close to high risk. Therefore, for the sake of the health of the fetus, pregnant mothers who are screened in the early Tang Dynasty and in the middle Tang Dynasty (nt and Down screening) must check on time.

Third trimester: the time period of deformation screening, fetal heart monitoring, amniotic fluid volume and placental maturity deformation screening is between 22 and 28 weeks. Generally speaking, the best deformation screening time is between 24 and 26 weeks. During this period, pregnant mothers need to do deformation screening to check whether the fetus has structural abnormalities, that is, the deformation of most organs and limbs in the body.

However, fetal heart monitoring should be done on time in the third trimester. Because fetal heart monitoring can be used to check the fetal heart rate, we can judge whether the fetus is hypoxic according to the results. As for amniotic fluid volume and placental maturity, we will check it during pregnancy, but we will focus on it in the third trimester. Because if the pregnant mother has less or more amniotic fluid, then the fetus may have some abnormal conditions, and the maturity of placenta is the maturity of placenta. If the placenta matures too fast, it is very risky for the fetus, because the placenta can no longer provide nutrition and oxygen for the fetus.

Therefore, during pregnancy, as long as the pregnant mother has passed these three levels, then under the condition that the fetus itself is normal, generally speaking, there will be no abnormal situation, and the pregnant mother only needs to wait for delivery with peace of mind. Of course, even if the pregnant mother has passed the abortion in the first trimester, nt and Down's screening, malformation screening, amniotic fluid volume fetal heart monitoring, it does not necessarily mean that the pregnant mother can wait for labor without worry. This is because pregnancy itself is full of risks. Even if the pregnancy test is normal, pregnant mothers need to pay special attention to their own safety in normal days.
